What steps will reproduce the problem?
(1) Load https://jsfiddle.net/p2amfxy9/

What is the expected result?
The two bordered tables should look the same -- each should be at its minimum intrinsic width & should wrap its text to 3 lines.

What happens instead?
Inexplicably, the first table (the one with 0px) doesn't respect its width at all -- it's the contents' full preferred width, as if it had width:auto.

Please use labels and text to provide additional information.
This testcase simply has two copies of <table><td>a b c</td></table> with width:0px on the first and 1px on the second.
Here's a slightly larger testcase with even more sizes: https://jsfiddle.net/u3dq3y0f/  As you can see there, progressively-smaller "width" values produce progressively skinnier tables (down to the minimum intrinsic width), EXCEPT that Chrome seems to have some special case that rejects 0px widths.

Firefox (54) and Edge (14) both produce "expected result".  So this is a bit of an interoperability issue.
